Fsl-Image-Gui does not give GUI upon HDMI connection

ajayvenkatakris — Thu, 15 Dec 2016 12:10:09 GMT

Hi,

I have built the Fsl-image-gui with the help of the 10 step guide for the yocto project. The image is working but there are two problems, The board I have built the image for is the IMX6DL SABRE AUTO board.

1)Upon HDMI connection, I am getting the tty console rather than the GUI itself

I have altered the uboot parameters required for the HDMI connection

setenv mmcargs=setenv bootargs console=ttymxc0,115200 root=/dev/mmcblk1p2 rootwait rw video=mxcfb0:dev=hdmi,1920x1080M@60,if=RGB24

saveenv

2) If i connect the ethernet cable to the board, I am not able to access the internet and download using apt-get. Also it does not give a specific IPv4 Address. Previously I had tried using the MFG tool, and when I had connected the ethernet cable I was able to get internet access and I was getting an IPv4 address. What could be the reason for this?

Hello,

Generally HDMI environment settings are described in the following thread.

HDMI Audio Setting

Offten problems relate to incorrect U-boot environment setting.

Also, please verify if HDMI is configured in kernel, using HDMI "Linux Menu Configuration Options",

described in "i.MX Linux® Reference Manual".

2.
As for IP : please use dhclient (udhcpc) to get IP address.

Note : apt-get is not provided in our Yocto BSP.

apt-get not working
